Most Recent Update: 30 January 2015.

This website presents population change information for more than 400 species of North American birds, as estimated from the North American Breeding Bird Survey. Estimates of trend (interval-specific estimates of population change), annual indices of abundance, and maps of abundance and population change for these species are presented for a variety of regions.

This website contains the 1966 - 2013 BBS analysis results. Although the website has undergone internal review, we caution users that errors may still exist in interactive programs and summary analyses. See our disclaimer for additional cautions.

1.We welcome comments on the results presented here. Public review and feedback regarding the results are a critical part of the scientific review of the website, and we thank you in advance for taking a careful look at these summaries.
2. Bird species names have been updated to conform to the 2012 AOU Checklist Update .

Survey Results

• Summary information on population change by region and time period


• This program allows you to display trends for 2 time intervals, by species. Indices are provided as links from the species names


• This program allows you to display trends for 2 time intervals, by region. Indices are provided as links from the region names


• These are relative abundance maps, estimated over the interval 2008-2012.


• These are maps of population change, based on the 1966-2013 interval.

Analytical Tools

• This program provides access to all information, for any species, on any BBS route. (Updated to 2013) New:For US routes, we provide summary information on remotely-sensed habitat data.


• This program allows you to estimate population change for any species and time interval (1966 - 2013), in any region covered by the BBS


• This program is for estimation of species richness from BBS data using capture-recapture based estimation procedures.


• This link leads to a website that allows users to download GIS data for the BBS.

Learning Tools

• This link transfers you to the Bird Identification InfoCenter, in which is contained pictures, songs, and identification tips of most North American Bird Species.


• Test your skills of identifying North American bird songs, pictures, and breeding and wintering distributions.
